These gif files offer a quick-look at recent recordings of the
BDSN and cooperation
stations in USArray. These images are generated
automatically every 10 minutes from the
Make
Your Own Seismogram tool and illustrate the last 24 hours of data
from the vertical component seismometer at each station.

We have selected a subset of
the stations from our network
(see this
map to find where the stations are located).
We will change the stations from time to time, to reflect areas of activity
as well as to avoid problems with telemetry outages.
Each station is plotted with the same amplitude scaling, so comparisons
between plots are possible (however, the data are not corrected for
instrumental variations from station to station). Noise characteristics
vary from site to site, and from day to day.

For comparison, you may be interested in viewing
sample seismograms showing local, regional, and distant earthquakes.

If you want to see whether the wiggles on the seismogram correlate
with recent earthquakes, you can check the maps of recent earthquakes
hosted by the UC Berkeley Seismology Lab and the USGS.
The long period nature of these records will emphasize large, distant
earthquakes rather than small, local events. We hope to provide
additional seismograms in the future which will show local events more
clearly.
